I ended up buying a new wireless charger, since I wanted one which would sit my phone upright on my desk. I ended up buying
this one by Itian for about $19, and they have the same charger available in different colors. It is capable of fast wireless charging, if the iPhone ever supports it and you use a 10W power brick with it; it also allows you to charge your phone in both upright or on its side (portrait and landscape mode). The charger has a USB cable built in but does not come with a power brick.
I also, for times I want fast charging, bought an
Anker 30W USB-C power brick -- just realize you'll likely also need to buy a USB-C to Lightning cable. At under $22, it is less than half of what Apple wants for their 29W charger. I've also seen the
Aukey Amp Duo recommended, as it comes with a second piece, which plugs into the USB-C port, that converts it into two USB-A charging ports.
